STUFF YOUR BRAIN SAYS:“The Upside of Irrationality,” Dan Ariely’s follow-up to his 2008 best seller “Predictably Irrational,” hits the hardcover list at No. 12 this week. Ariely, a professor at Duke, is a leading researcher in behavioral economics. One of the field’s concerns is the way we tend to misjudge future pleasure — for example, by imagining that a new Ferrari will make us feel much happier than it actually does. But making The New York Times best-seller list, it turns out, really does feel good. “When my first book reached the list, I called my wife to tell her and I was just not able to talk from excitement,” Ariely said by telephone. “This was very interesting to me because I was very happy to hear the news, but somehow sharing it with someone I love intensified it to an extent that was just too much for me, and I was just able to say a word here and there and almost cry in between.” The differences in our experience of emotions when we are alone versus with others, he added, might be a fruitful avenue for future research.
